ROLLER-B Original application filed April 18, 1916, Serial Ill'o.91,989. Divided and this application filed 1916. Serial No.91,990.

To all whom it mayconcem Be it known that I, An'rn'on M. LAYCOCK, asubject of the King of Great Britain, residing at Kingston, county ofLuzerne, State of Pennsylvania, have invented certain new and usefulImprovements in Roller-Bean ings, of which the following is aspecification.

vmeans whereby the bearings may The invention relates to rollerbearings. Its principal objects are to provide a iimple e assembled andthe rollers held in pbsition against axial displacement. Other objectswill appear from the following description.

The bearing comprises inner and outer j rings with interposed rollers.These rollers are prevented from axial displacement by suitable meanswhich includes a split contractible ring carried by the inner ring. 99

This application is a division of my application Serial No. 91,989 filedApril 18, 1916. The various features of the invention will be understoodfrom an inspection of the accompanying drawing, in which,

Figure 1 is an end elevation with part of the inner ring broken away toshow the contractible split ring;

Fig. 2 1s a half side elevation and half sectional view; t

Fig. 3 is a perspective view of the split ring - The bearing comprisesan inner ring 10- and an outer ring 12. As shown, the bearing is of thetwo row type, although the invention is applicable to other types. Theinner ring is provided with a medially located outwardly extendin radialflange 11, and the outer ring may be provided with an inwardly extending,radiahflangle 13, 14 at eachend. Inter-posed between t e flanges 11,13, 14-are two rows of roller bearings 15, 16. One of the flanges in theouter ring as 14, is provided with an opening 17.v This .opening is forthe purpose of passing the rollers into or out of the bearin and may beof any shape that will acco'mp ish this result. In Fig. 1 this openingis shown as arcuate, being substantially semi-circular in outline. Inthe inner ring and opposite the Specification of Letters Patent.

April 19,

flange 14 a groove or slot 18 is formed, adapted to receive and seat acontractible till] split ring 19; As shown, the split ring prorollers 15and blocks the opening 17 against egress of the rollers. When the splitring is in the groove 18, the ends 23, 24:, thereof, abut. Thusthe ringis continuous, and the face presented to the ends of the rollers issmooth and without interruptions.

In assembling the bearing the row of rollers 16 and inner and outerrings are put together in the usual way. The row of rollers 15 is put inplace by inserting the rollers one by one through'the opening 17 andpushing them around in the bearing race-way. When all of the rollers 15are in place, split ring 19 is expanded to slip over the inner ring, andis pushed inward until it seats in the groove or slot 18, with its ends23, 24:, abutting, and

Having thus described the invention, what is claimed and'desired to besecured by Letters Patent is:

In a roller bearing, an inner ring, an outer ring, interposedcylindrical rollers having flat ends, means for preventin axialdisplacement of said rollers including a flange carried by the outer ofsaid rings, said flange formed with an opening through which the rollersmay be inserted and having a flat surface in contact with anend of therollers, the inner ring being formed with a groove opposite said flangeand a split ring seated in said groove and having a flat surfaceabutting the said end of the rollers for preventing egress of the samethrough said opening.

In testimony whereof I afix my signature.
